Homework Statement Pulsars are neutron stars that emit X rays and other radiation in such a way that we on Earth receive pulses of radiation from pulsars at regular intervals equal to the period that they rotate. A certain pulsar has a period currently of length 33.085m/s and is estimated to...

Homework Statement A pulsar emits bursts of radio waves with a period of 10 ms. Find an upper limit to the radius of the pulsar. Homework Equations Not Sure The Attempt at a Solution Can anyone help with this, I cannot see how the period will help tell you the upper limit to the...

Often I will hear quoted such and such Pulsar has a period of X and a Pdot of Y. However this is somewhat ambiguous to me. If the period is changing, then how does one quote its period? Obviously, by using some unambiguous standard that I am unsure of. Is the reported period (in a paper...

I feel stupid for asking this, but the book I'm working through doesn't explain it at all, and I want to make sure I am correct. The book is Fundamentals of Physics, by Halliday. This is problem #16 after the first chapter. My solutions for A and B (please forgive me if my tex isn't very...

http://en.wikipedia.org/wiki/Millisecond_pulsar How do these pulsars remain intact?

A pulsar is a rapidly rotating neutron star that emits radio pulses with precise synchronization, there being one such pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. At present, the pulsar in the central region of the Crab nebula has...

Anyone got an idea of where I can get some information on the mechanics of binary pulsars? Especially the Lagrangian formulations are of interest.

Soo... I'm trying to "sync" something up with PSR B1919+21. (so in essence I'm just looking to have an indication (preferably audio) of its cycle/period in real time. (PSR B1919+21 has a period of 1.337 seconds and a pulse width of 0.04 second.) I'm wondering if there any online streams of...

A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. The pulsar in the Crab nebula has a period of rotation of...

A pulsar is a rapidly rotating neutron star that continuously emits a beam of radio waves in a searchlight manner. Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the Earth receives a pulse of radio waves. For one particular pulsar, the time between two...

Hello! I just want to know how does a pulsar die, if it dies someday...? :bugeye:

I'm still trying to locate a particular pulsar which had (in 1972) the original designation CP1133. :confused: Does anyone here happen to have a catalog or reference which will allow me to find which pulsar (or the current designation & info on such pulsar) that had an original (early...
